Google rates websites on their length, meaning web developers now have to push to reduce the amount of code on their websites. Something that has proven worthwhile after research is to move all of the head information to a seperate file, this achieves two things. Firstly the site has a much smaller amount of code on it, which means its going to rank higher for seo and secondly, it is worthwhile because the time saved making the entire site adds up when you consider you only have to edit the head once to effect every page.
This is something I wanted to practise before creating my next project, so below is an example of this completed.
First the index.html file where the head holds the php include;
Secondly the head.php file which has all of the head data for the site;
Finally the stylesheet.css is connected through the head file;
This makes the website appear as normal, but the previously mentioned benifits.
